etc. It is one of the objects of this inventlOHtO'PIOVlClQ a magnetic deviceof a snnple and economlcal constructlon for abstracting such foreign articles. It anothero-bject of the invention to provide a separating devlee of this character with a simple and: efficient ineans for effecting thoroughly the lfinalwremoval ofthearticlesseparated.

:Like reference cha actors .refer to like parts throughout the :followingspecification and the several figures of the accompanying drawing.

Referring now tothe drawing, .10 indicates the frame of a cotton breaking and mixing machine, .in which .is rotatably mounted the shaft llof a band conveyor 12. Thisconveyer12 maintains a continuous forwarding movement, .and is provided with a plurality of pickers, which pick up the cot- ;t0n from asupply hopper and carry it over to a delivery box, with :the result that :the

-cottonis broken up-amlmixed in the process.

Abal' 15. extends between the plates 14; directly above, andparallel avith the axis .of, ;the

shaft 11. To the endsiof thegbar .15 are-secured by :meansio-f angle irons 116, levers 17. :One of @the levers 17 .is pivotally connected, at 18, withieach of the plates .14. fl hecross bar 15 carries a plurality of electro-magnote 19 of such dimensionsithat theirlower ends are situated close to the conveyor 12, when the parts are in the position shown in Figs. 1-3.

Rotatably mounted between the plates 1% is a shaft 20 carrying at one end a pulley 21, which is connected by a belt 22 with one of the pulleys, as 23, of the cotton breaking and mixing machine. The shaft 20, which is thus continuously rotated, carries a cylindrical brush 24 which extends throughout the entire distance between the plates 14. A rope 25 or the like is connected to one of the levers 17, by pulling upon which the bar 15 can be shifted from the position shown in Fig. 3 to the position shown in Fig. 4:, in which latter position the outer endsof the magnets 19 engage against the rotating brush 24. By releasing the rope 25, the bar 15 is permitted to return to its original position. V

In order that current may be shut ofl from the magnets 19 when it is desired to remove therefrom any articles which may have adhered thereto, I provide a switch which is adapted to be engaged and opera atecl by one of the levers 17, when the parts are in the position shown in Fig. 4. In the construction now being described, this switch is mounted upon the plate 14; shown at the left-hand side of Fig. 1. The switch includes an inclosing casing 26, carrying a pair of binding terminals 27 which are connected in series with the circuit of the electro-magnets. Mounted within the casing 26, and electrically connected with the binding terminals 27, are a pair of springs 28, carrying attheir ends carbon blocks 29, which are normally in contact with each other. Secured to the lower spring 28,- and passing loosely through the upper spring and through the top of the casing 26, is a plunger 30. It will be seen that when pressure is exerted downwardly upon the plunger 30, the blocks 29 will be separated, thereby breaking the circuit through the electromagnets. When the pressure is removed, the blocks come togetheragain and reestablish the circuit. The switch is so positioned that when'the magnets are swung into the position shown in Fig. 4, one of the levers 17 will strikeandpress downwardly upon the plunger 30, thereby breaking the circuit through the electro-magnets.

The plates 14 are provided with guides for receiving slidably the ends of a tray 31, which has a guard plate 32 extending upwardly to the'rear of the brush 24:. In the operation of the device, the magnets are normally in the position shown in Fig.3, in which they pick up any iron particles which may be present in the cotton passing beneath them. When it is desired to remove these particles from the magnets, this is ef- Copies of this patent may be obtained. for

what I claim asnew'and desire to secure by Letters Patent is:

The combination with a cotton breaking and mixing machine having a niaterial- I conveyer, of means thereto for separating iron. or steelparticles from the material to be carried by said conveyer, said separating means comprising detachably secured a plurality of electromagnets, areceiver, a.v

rotary brush associated with said receiver, a normally, stationary pivoted U-shaped frame for supporting said electromagnets in cooperative relation with said conveyer,

means for rocking said frame to bring said electromagnets' into cooperative relation with said receiver and into engagement with said rotary brush, whereby the latter brushes the particles from said electromagnets into said receiver, an electric switch.

controlling the circuit of said .electromag nets, and a plunger for actuating said switch, said plunger being disposed in the path of one of the arms ofsaid U-shaped frameso'as 'to be operated thereby when said frame is swungvto bring said electromagnets into engagement with said brush.

In testimony whereof, I the said MONT- s5 GOMERY SLEETH, have hereunto set my hand.
